Having thus fully described my invention, 5 what I elain-i as new and useful is InY` a surface-saw, two sections similar in design and adapted to be clamped together by screws, said sections being curved upward at one ond, a blade clamped between the seeio tions, eac'h of slaidseetions having recesses formed on their inner faces; said recesses slanti-ng downward toward Jdie curved end andforining sockets, a handle having projections adapted to lit in said socket-s, substantially as set forth.

In testimony whereof I have hereunto affixed niysignatnre in the presence of two subscribing witnesses.
